Anode Materialshigh-performance anode materials for Lithium-ion Battery Manufacturing
Targray Anode Materials for Battery Manufacturing
Targray offers a complete portfolio of anode materials for Lithium-ion battery manufacturing. Our anodes include natural & artificial graphite, SBR & PVDF binders, and high-performance copper foils. The anode materials offered are all high-performance materials fitting perfectly into your battery manufacturing.
A Lithium-ion battery is typically comprised of film electrodes that are arranged on metal foil current collector. The electrodes range in thickness from 40 to 120 µm. Carbon materials in the negative electrode serve as conductive agents as well as electrochemically active materials. They are then mixed with binder/solvent and additives, and applied on a copper foil which acts as the current collector.
Active Anode Materials
The anode (or negative electrode) in Lithium-ion battery is typically made up of Graphite, coated on Copper Foil. Graphite is a crystalline solid with a black/grey color and a metallic sheen. Due to its electronic structure, it is highly conductive and can reach 25,000 S/cm2 in the plane of a single-crystal. Graphite is commonly used as the active material in negative electrodes mainly because it can reversibly place Lithium-ions between its many layers. This reversible electrochemical capability is maintained over several of thousands of cycles in batteries with optimized electrodes. However, one requirement for this application is that the Graphite surface must be compatible with Lithium-ion battery chemistry (salts, solvents and binders).
Targray supplies a portfolio of Binders materials: Styrene Butadiene Copolymer (SBR) and Polyvinylidene Fluoride (PVDF), used in the cathode and anode electrode slurry making process for Lithium-ion batteries. Binders such as SBR and PVDF, are used in Lithium-ion batteries to hold the active material particles together and in contact with the current collectors i.e. the Aluminum Foil (Al foil) or the Copper Foil (Cu foil).
Targray offers a range of Copper foils depending on the application of the Li-ion battery. A rolled foil (RA-type), made from wrought Cu is generally used for high-energy, high-power applications such as drivetrain and power tools. An Electro-Deposited (ED) foil is used in high-energy, low-power applications such as Li-ion batteries for cell phones, laptops and consumer electronics. Nickel foil is electro conductive, and is used when there are requirements for its high anti- corrosion properties and ultra-thinness. It can be produced wider and thinner than the more commonly used rolled Copper foil.
